Application filed. December 10, 1926. Serial No. 153,847.

This invention relates to methods of and apparatus for chargingcontainers with material such as ice cream, and consists in improvementswhereby this operation is improved, simplified and expedited. Thisapplication in part is a continuation of my prior co-pendingapplication, Serial No. 654,147, filed July 27, 1923. V i

The invention will be best understoodby reference to thefollowing}description when taken in' connection wtih the acconipayingillustration of one specific embodiment thereof, While its scope will bemore particularly pointed out in the appended claims.

Referring to the drawings andto the embodiment of the invention, whichis herein submitted for illustrative 1 urposes only, the" i creamcontained in each con'ipartment of the The bed plate '11 has the upmeans:i we in provided between the bed plate ll and supporting plate 19 topermit the introduction beneath the charging chamber ofa container to becharged. 7 n

' lce cream 18 introduced into the open top of the supply chamber 21(Figs. 1 and 6) preferably in an approximately one-third downwardlyconverging rear wall. Forthe purpose of charging the container with icecream of several ditl erent flavors it maybe fillVlClGtl into severalcon'ipartments of substantially equal capacity bymeans of thelongitudinal partition walls 23, forming herein three compartments orsub-divisions, ,each oi which Is filled with ice cream of dif- "feringflavors. For a piirpose'to be laterde scribed, the lower part of thesupply chamber is provided with a jacket25 containing pipes QTthroughwhich there may be circulated brine or other suitable cooling orfreezing liquid, the pipes being externallyprotected by an insulatingcovering 29.

The supply chamber has bolted to the bottom thereof a casting whichpresents a dclivery orforming chamber 31 communicatf 'ing therewith thedelivery chamber being herein longitudinally separated into threecompartments or si'ib-divisions by the parti-h tio'ns 33which'constitute extensions of the partitions Jl in the supply chamber,the bottom of each compartn'ient of the. supply chamber terminating in arectangular opening which registers and communicateswith thecorresponding underlying coin'partn'icnt in the delivery chamberQ Thedelivery fchan'ibei'is also preferably surrounded by a jacket 35containing pipes 37 through which the freezing mixture may becirculated, suchsupply chamber is delivered to the correspondingunderlying compartment in the nelivery chamber. such deliverybeingassisted by means which-exertpressure from behind the ice cream, servingto crowd or force it 7 into the de] such ery chamber. -Here i'id d toreaeh wnii par m. at of.

each compartment ofthe charging chamber.

As they move forward, the hinged blades of the pusher-s 73-serve notonly't-o force the ice cream ahead of them, but also act to clear thesidewalls and partitions of the delivery chamber of the accumulation ofhard frozen particles of ice cream which might otherwise clog thepassage and build up'to interfere with the action of the moving parts.

, During the time that the ice cream is being forced into the chargingchamber, the honzontalcut off valve 69 is positioned to close pel thecharges of ice cream contained therein through the underlying opening 63and into a suitable container which meantime has been positioned beneaththe same.

The container, which may be an ordinary pasteboard carton 81 (Fig.carried, if dew sired,'w1thin a suitable metal form or cage,'is

"carried by the container support 83 (see Figs.

.1 and 3).

While the charging chamber is being charged, the container 81is'manually placed on the container support and the latter raised bymechanism, to be hereinafter described, to bring theopen mouth of thecontainer in firm abutment against the bottom of the'plate 19 and inregistration with the discharge opening'63 so that it" may be firmlyheld to receive the charges ofice cream which are thus expelled from thecharging chamber under-pressure of the plunger 65.

In order to keep the sides of the charging chamber clear of accumulatedfrost, suitable means are preferably p'rovided, the same hereinconsisting of'the scraper blades 85, one of which'is carried by eachopposite side of'the plunger to engage with the chilled sides of "thecharging chamber, the plunger fitting the char ing chamber with a slightclearance over.

WlllCItliQ-SCFRPGIS extend. The latter are set at an acute angle so thatin the downward movement of the plungerthey engage with and clear theside walls of the chambero'f any, accumulated frost.

clearing devices on the'two opposite chilled sidewalls will suffice. V

The 'SPGClfiC formof charging machine herein illustrated is intended tocharge the carton with three charges of ice cream of different flavorseach in brick orblock form, but,

by rearranging the partition walls, the machine may be constructed todeliver a different number of flavors, or it'may be constructed withoutsuch partition walls for the charging pending application Serial No.163,382.

The machine is especially advantageous in charging, cartons each with aplurality of separated individual portions, each to contain aproportionate partof the three or other number of flavors employed, thecarton having been previously prepared withseparating walls, as,forexample, those presented by 'wax paper held therein by temporaryst-iil'ening partitions, such as described in the afore said applicationSerial No. %,14-7, or my co- In case individual portions are deliveredto the cartons, prepared as there described, the bottom of the plunger65 may be provided with an end plate 87' (see Figs. 3 and 5-) which maybecoiiveniently formed of rubber, such plate having a' series of groovedrecesses extending in'a direction transverse the underlying carton 81,which recesses are adapted to [it over theupstanding partition walls incase the latter pro ect slightly above the top of the carton. Whetherthe grooved plate as de- HIFH. 1 u sciibedis ei pioyeeioi 1 m 1I1( iviua poi tions or the piston is provided with a plane ungrooved face forcharging the carton with a single brick, the lower face of theplunger isproportioned so that its lower face, or the lower face of the plate 87,lies in substantially the plane of the top of the carton when theplunger is projected, thereby crowding the charge into the carbon-tosubstantially fill. the

Referring now to themechanism operating the moving parts described, theformer is driven by the motor '91 mounted on the bed plate 15 andconnected through a suitable reducing gear to drive the large gear 93journaled in the bracket 95.- The gear 93 has eccentrically mountedthereon 97 the link 99 connected to the lever 101 which is pivoted at103 to the bed 11 of the machine and at the opposite end is jointed tothe upright'link 105. As the gear turns and the link 99 is raised andlowered the lever 101 oscillates, reciprocating the link 105 and alsooscillating a bell crank lever 107 pivoted at 109 on the The link 105 ispivoted to one arm of the bell crank, the opposite arm tl191'0 of beingconnected to the horizontal rod 111.

For this purpose there arebolted to the side of the leverarin 113 engage with a groove twoshortarms 'l-ll-land 121 which are united at their opposite ends tocarry a roll 123,-tho latte-r engaging the under side of a rea *ward- 1ypr ecting'link 125. The connection of the arm 119 tothe lever 1'13is'adjnstahle'so that its .positioninay be altered to raicc or lower theheight 01 the roll 123. The link 125 is jointed at its opposite-end toa. lever arm 12'. and also a. link 129 to which is connected a lever arm131 (see 1 and 3).

To thus actuate the containersupport 83, the latteris mounted on tour vertical pins 185 (Fig. 3) guided in the plate 11 andconnected below theplate to a crosshead 187 adaptedto be raised andlowered by a rod'189 connectedito the bell crank lever 191, the oppositearm of which -ari'ies a cam roll 193 adapted to engage with a cam rise195 on the, opposite side of the gear to the cam rise 181. The cam rise195 overlaps in its angular position the cam rise 181, so that the bellcrank lever is moved to raise the container from the supporting positionto receive the charge just before the cam roll 1'79 drops off fromthecam rise 181 to openthe valve 69 and close the valve 59. In

order to exert a yielding pressure against the container support andpress the mouth of the container hrmly against the under side of theplate 19, the bell crank lever191 is con-j nected to a sleeve197 shdablymounted on therod 189 and acting against the cross head 18''! throughthe spring 199.- Springs 201 are mounted on the pins 185 between the bedplate 11 and the cross head 187 to positively drop the container supportwhen the canirise 195 .passes out from under the cam. roll 1.93.

In the operation of this machine, the supply chamber 21 is filled andits compartments replenished from time to time as may be required withthe different flavors of ice cream selected for charging the container,

such cream being introduced into the supply chamber preferably in acondition commonly termed one-third frozen, or that which is had bymaintaining the cream at a temperature in the neighborhood of 26 F. Inthis condition it appears as a thick pasty, semi-fluid mass. As thecream passes down through thesupply chamber it is subjected to theaction of the cooling pipes 27 and becomes somewhat.

' separatedlayers of cream ofdiilerentflavors harder or stiller, whichcondition becomes further intensified after it has been delivered intothe delivery chamber, where it is subject- 7 ed to theaction of thecooling pipes 37 which act also on the cream after it has been deliveredinto the charging chamber.

The cooling liquld is brought to the machine through the supply pipe 211and the branch pipes 213 and 215 for the cooling pipes 27 and 87respectively, the valves217 and219 being provided so that the-supply canbe regulated to suit the conditions required.

The cooling or chilling action of these fl pipes is preferably soregulated that the cooling and hardening of the ice cream is progressiveas it advances througlrthe supply chamber and dcliverychamber to thecharging chamber, so that when delivered to the charg ing chamber it hasreached a relatively stiflfl formative and non-fluid state where ittends to retain he form imparted-to it. This con ditio-n may be reached,for example, by so. graduating the freezing action that the cream,before being discharged from the charging chamberinto the container, isbrought to whatisknown as a two-thirds frozen condition, or that,"reached by a freezing temperature in the neighborhood of 20 F, underwhich condition the moisture becomes stiff and nonfiuid, holding theform imparted to it;

At each operative cycle of the machine, therefore, there is forced intothe compartments of the delivery chamber from the rela-' tively soft icecream ofthe supply chamber compartments a charge of ice cream whichgradually becomes stiili'er and harder as it advances. The entrance fromthe supply cham ber compartments is thereuoon closed, the valve betweenthe changing chamber and delivery chamber i r'a i sod. and the severalcharges 'otrelatively .iardened ice cream, approaching the two-thirdsfrozen condition, are pressed or crowded by the pushers into thecharging chamber, the delivery valve of which at that time is closed andthe plungerraised, so that the charges are compressed into the severalcompartnients of the charging chamber in substantially the form andshape in which they are to be delivered to the carton. The valve betweenthe charging chamber and the delivery chamber thereupon closes, the de-'livery valve is opened and the plunger descends, forcing'the cream,which by this timehas reached the stiff and form-retaining state, intothe underlying carton, the open mouth of which meantime has been pressedagainst the mouth of the charging chamber.

Accordingly, the creamwhen discharged from the charging chamber intothecontainer is in such a hardened state that the cream from the severalflavors cannot run together and intermingle in the container, but thedif-- ferent flavored bricks or blocks maintain a distinctline ofseparation or cleavage.

Where itis attempted to discharge uninto the same container, if thecream is in a soft, plastic, pasty or semi-frozen condition,

represented, for example,by the one-third frozen condition, the softcream from the adjoining layers. tends to run together. Furthermore,when the charged container is subsequently placed in the hardeningchamber to bring 1t to the full frozen condition, which .may, forexample, be represented by 0 F.,

and, presenting a coarse,crystalized structure on the exterior insteadof the smooth and finely grained texture which is desired. Filling thecontainer with the soft cream also tends tobulge the carton after thehardening. or final freezing action due to the expansion of the creamWhen subjected to the final freezing.

By charging the container as herein described withcream which has beenbrought to the hardened or two-thirds frozen condition, not only aretheseveralbloclrs n'iaintained in distinct and separate layers, but thetendency of the moisture to Work to the sides of the brick is prevented,providing a cream of smoother and more desirabletexture, and there islittle or no tendency for subsequentexpansion and bulging of the cartonunder the final hardening and freezing action.

Incharging a container with the cream in a hardened or formative state,I [ind it desirable that the cream should be first forced into aclosedforming chamber, as, for example, the one illustrated in the drawings,the. com} art'ment or compartments of which havesubstantially the shapeand dimensions of blocks or units o f'the' form in which the cream istobe delivered to the container. To expel the blocks or. units of thehardened cream 'fronr such chargingchamber I also find it' preferable toemploy a positive expressing device, such asthe plunger 65, Working, inthe charging chamber, so that the ice cream of each individual flavor,instead of being forced out as shapeless mass, is. formed Within thechamber anddelivered therefrom to the containerin the shape and form itis to occupy therein. This, of. course, is subject to the possibilityofseparating the brick Within-the container into individual portions, asheretofore described, Wl'rere each individual portion receives adefinite amount of 191 a-Y It will also be observedthat thei'ce' creamin passing first from thesupply chamber to the delivery chamber and fromthe delivery chamber to the charging chamber, and thence from the.charging chamber to the container,

is subjected to a succession of compressing, or expressing actions,andthat the accumrn lati on oi? hardenechfrostf crystal's'adj acent thesides of these various chambers,and 'ivhieh' would otherwise interferewith the" operation of the machine because of the progressive hardeningaction imposed on the cream. is

kept. cleared an'd reduced by the actionof the scrapers described;Obviously other clearing. means for maintaining the side a lsot theVarious compartments tree from such frost accumulation might beemployed, but the scraping action offers a simple and practicalexpedientfor this purpose. i I

While I have herein sh'own fortlre purposes ot'ill'ustration onespecific embodiment of the invention, it is to be understood thatcxtelrsive deviations may be made from the l'orm and relativearrangement of parts and that Widely difilerent applications may be madeo i the invention or individual features thereof, all Withoutdepartingfrom the spirit oi the invention.
